Wall spacer for IKEA KNÖCKLA pedal bin, 50l

I bought the KNÖCKLA pedal bin, every time that I used the pedal, the bin moved towards the wall.

This spacer fits in the slot at the rear of the bin and keeps it away from the wall by 25mm (1 inch).
This spacer requires no screws to install, it is a friction fit. It just slides onto the rear of the bin and can be removed easily. 
The spacer uses less than 65g of filament, printed in PLA.

Please note: KNÖCKLA pedal bins are injection moulded and therefore can vary in size at the edges.
